The 1,262-acre Tully Lake property is managed to sustain a healthy ecosystem for future generations. The thriving biodiversity of the Tully River Valley and the interconnections of our forests, wetlands, waters, and wildlife are valued and managed for the long term. Tully Lake is home to a wide variety of wildlife, from tiny insects and song birds, to large mammals such as deer and moose. Fifty-five percent of the reservoir area is wetlands, providing habitat for fish, waterfowl, song birds, insects, reptiles, amphibians, and mammals such as beaver, mink and otter. The rest of the property provides habitat for upland species such as deer, coyote, fisher, owl, fox, raccoon, skunk, porcupine, rabbit, and squirrel. The forest within Tully Dam's reservoir area is composed primarily of white pine, providing habitat for owls and woodpeckers, red-tailed hawks, and white-tailed deer.
Recreation: Tully Lake offers many opportunities to enjoy the outdoors. Activities in and around the lake include mountain biking, camping, disc golf, hiking, picnicking, boating, and fishing and hunting in the appropriate seasons.
Nearby: When visiting Tully Lake there are several opportunities for visitors to explore in the surrounding area. At the north end of the lake there is a tent only campground run by the Trustees of the Reservations which provides a perfect launching point to enjoy the outdoor attractions nearby. Ten miles away is the Birch Hill Dam, another Army Corps project that provides miles of trails and river to explore. The Quabbin Reservoir is also within a short ten mile drive of Tully Lake and serves the city of Boston as its water supply. The Quabbin is a unique area; there were four towns flooded to create it, and it has some of the most interesting blends of human and natural history in the region.
